Abstract
Medical 3D printing is a powerful tool for fabricating patient-specific implants (PSIs) that offer reduced surgical time, enhanced clinical outcomes, and costeffectiveness. These implants interact with the human body and must remain sterile and uncontaminated. Polyether-ether-ketone (PEEK), an excellent biomaterial, is widely adopted for 3D printing of medical implants but requires high-temperature conditions. This study explores the feasibility of a 3D printer producing sterile implants ready for direct implantation in the body. Two configurations of a medical-grade 3D printing machine are proposed, aiming to eliminate velocity fluctuations and eddy formations, to prevent contamination while optimizing heat transfer in the overall system during printing of PEEK implants. Computational fluid dynamics is used to investigate fluid flow dynamics to achieve laminar flow and sterility. Simulation results showed that both configurations could achieve laminar flow inside the 3D printer, ensuring sterility, while maintaining a suitable temperature for producing PEEK implants. The results showed that temperature changes inside the chamber and design changes were successful at regulating airflow and enhancing heat transfer. The successful design of the medical-grade 3D printing machine configurations, coupled with simulation results, provided valuable insights for further development and improvement of medical-grade 3D printing machines for PEEK implant production.
